MACHINE FOR FINISHING THE NECKS OF BOTTLES, 84C.

SPECIFICATION forming part of Letters Patent No. 416,559, dated December 3, 1889. Application filed October 10, 1889- Serial No. 326,586- (No model.)

'ington, in the county of WVashington and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Finishing the Necks of Bottles and Similar Articles; and I do hereby declare the following to be a full, clear, and exact description of tlie invention, which will enable others skilled in the art to which it appertains to make and use the same.

The object I have in View in the present invention is an improvement upon a machine described in a patent dated June 12, 1888, and numbered 384,290, granted to Harry Semple, and upon a machine described in a patent dated May 28, 1889, and numbered 404,311, granted to myself and Harry Semple.

The present improvement therein consists in a novel arrangement of the innerfingers or jaws with relation to the outer jaws.

The improvement also consists in new and improved mechanism for operating and controlling the inner fingers or jaws.

The improvement further consists in an improved construction of the outer jaws,

whereby the same are made movable, and

means for controlling and operating said outer jaws simultaneously with the inner fingers or jaws, all as will be fully described and claimed hereinafter. I

For a clear comprehension'of my invention attention is invited to the accompanying drawings, forming a part of this application, and in which Figure 1 is a side sectional view of my improvement; Fig. 2, a front elevation of the same; Fig. 3, a longitudinal sectional view taken on the lines a: a" of Fig. 1, and Fig. 4 a similar view taken on the lines y y of Fig. 1.

In each of the above views corresponding parts of the device are designated by identical letters of reference.

Since my present invention relates solely to the construction, operation, and relation of the outer and inner jaws of a machine for finishing bottles and jar-necks, I will describe only those particular parts which constitute the invention, and it should be understood, while my invention is especially applicable for use with the machines described in said erably in three pairs.

Letters Patent, that I do not limit myself to such a use, but reserve the right to apply my. invention to any other form of machine with which it might be used.

A represents the bed or base of the machine, supported by legs in the usual way, and uponwhich is mounted a shaft B, which is j ournaled in standard 0. The forward end of the shaft B is cut away, so as to form a spindle portion a.

Mounted on the shaft directly behind the spindle portion is a collar D, secured to the shaft in any suitable manner, so as to have the same rotative movement orback-and-forth motion which the shaft has. If preferred, a

revolving motion can be used instead of rotative. This collar is provided with a number of peripheral integral ears I) Z) Z), arranged pref- Pivoted within each of these pairs of ears is a finger-arm c, extending out a short distance beyond the collar D. On the outer end of each finger-arm is the inner jaw proper D, made of the desired shape and size and removably secured in place on the finger-arm by any suitable means, so as to be adjustable. Each of these finger-arms is provided with a short right-angled limb e, provided at its upper end with an enlarged head f. Mounted and keyed to the shaft B directly on the rear of the collarDis aclutchcollar E. By thus keying this clutch-collar E in position it is capable of a certain amount of independent lateral movement on the shaft B. Extending out from this clutch-collar are a number of curved arms 9 g g, corresponding in number and location with the finger-arms c c c and each being provided with a sockethead h, engaging with the enlarged head f of the short limbs e, so as to thereby form a knuckle-joint.

Mounted directly beneath the shaft B and supported by the standard C and the outer jaw-supports is a rod G, corresponding with the rod I of said Patent No. 404,311. Rigidly secured to the rod G- is a vertical arm 2', provided at its upper end with a yoke j, engaging with the peripheral groove 76 of the clutchcollar E, and by means of which the clutchcollar can be moved back and forth on the shaft B. The friction between the yoke and the clutch-collar can bereduced by frictionrollers in the usual way.

IOC

The support for the outer jaws consists of of a metallic plate G, secured in position to the base or bed of the machine by means of suitable bolts or screw-bolts passing through the angle-piece l of the same. This plate G- consists generally of a circular main portion m, having a large circular opening a therein, and which is rigidly supported by means of a short vertical standard 0, bolted to the bed or support, as before explained. The rod G extends through this standard and is partially supported by the same. When the outer jaw-support is in proper position, the end of the shaft B will be directly in the exact center of the opening 91, as shown. Extending entirely around the opening at isa flange 19,. having a flat front face and circular outer and inner faces, as will be. apparent. This flange is provided with, by preference, three dovetail mortises arranged diametrically with the center of, the openings 11. Engaging with each of said dovetail mortisesis a corresponding-shaped tenon q, made integral with each of the outerjaws H. When theouter j awsare brought together, thetenons q moving in the dovetail mortises, as will be evident, the shape thereof is circular, witha central opening 0', somewhat smaller in size than the opening 11. Around the opening '7' is a flange 3, having its interior face of the exact shape of the outside of the neck of the bottle. M y e e A collar or ring 6 extends around the flange pdirectly behind the integral tenons q, and isprovided with an inclined slot n directly in line with each tenon. Engaging with each of these slots is a pin 1:, passing through each of the outer. jaws and its respectivetenon. It will now be seen that'as the collar or ring is movedfrom one side to the other .the pins '17, engaging with the slots u, will move the aws back and forth on the dovetail mortises,

and the jaws will be opened and closed,

thereby enlarging and contracting theopening a forthe entrance of the bottle-neck.

At the lower portion of the collar 2' is an ear I, having a slot J therein, through which the rod D extends. This slot is sufliciently large to allow a considerable movement of the ear I from side to side.

An adjustable collar K is secured to the shaft G,preferably by means of a set-screw u", and is provided at its forward end with an incline w. By making this collar adjustable the incline can be caused to enter the car at any part of the movement of the rod G. In this way the movements of the two sets of jaws with relation to each other can be regulated.

Mounted upon the spindle a is a disk-piece K, arranged so as to entirely close the opening 0' between the outer jaws when the said jaws are closed. Suitable slots 1 are formed 011 this disk-piece K, so as toallow for the movements of the inner jaws. The outer jaws are kept normally opened by means of a coiled spring L, secured to the ring or collar [and tending to keep the pins "U at the top of the slots 14. The inner fingers or jaws are kept normally retracted by means of a coiled spring .2, attached to the yoked arm and tending to move the clutclrcollar 1* toward the collar D, and thereby bringing the inner fingers toward each other.

The operation of the device is as follows, the parts being in their normal positions; The shaft B is rotated by any suitable mechanism or is rotativcly moved back and forth, as explained in said Patent No. 404,311. This motion is communicated to the collar D, and the inner fingers and disk are moved with it. A bottle having its neck suitably heated at a glory-hole or by other snitablemcans is now presented toward the jaws by any convenient means, preferably by means of a casing secured to'ahanda'od, Thcneckof the bottle is introduced between the two sets of jaws, and its month eases into contact with the revolving dislg so as to thereby be smoothed and perfectly shouldered, It will be now seen that by forcing the rod Gin wardlythe clutchcollar will'benioved laterally on the shaft'B, and by reason of the intermediate mechanisin before described the inner jaws will be separated and will a roac the outer jaws and will engage with and form the inside of theneck of the bottle. This same movement of the rod G will cause the incline a: to enter the ear I, and the ear I will be moved to one side, thereby partially rotating the collar or ring o and causing the outer jaws to'close and approach each other and engage with and form theoutsidc of the neck of the bottl e. \Vhen the bottle-neck is finished,the rod G is reversed by means of thespring 2, thereby disengaging the inner jaws froi'nthe inside of the neck and unlocking the ear of the ring f. The outer jaws now open automatically by means of the spring L, and the bottle can be removed and theoperation repeated. In this way theneck of all kinds of bottles and otherlike articles can he finished by simply changing the two sets of jaws to correspond with the work desired, and the work of finishing can be done in a much bettermanner and in less time and with less labor than heretofore. Moreover, practically no experience is required on the part of the operator to handle the machine.

\Vhat I claim is-- V 1.
